The unguentous or jelly-like product may also be converted into pulverulent bodies by adding suitable solid substances suchas for instance magnesium carbonate or talcum or a plurality of such substances.

During or after the production of the novel preparations additional constituents may be added, forinstance substances adapted to improve the smell of the products or substances which exert a cosmetic or therapeuticeffect. The smell may for instance be improved by adding eucalyptus oil, lemon oil, rosemary oil, thyme oil, mirbane oil or camomile oil or a plurality of these substances. Also formaldehyde, paraformaldehyde and a great variety of othersub'stances or bodies may be added to the products.

The novel process may be used for converting mineral oils of any kind into jelly-like or unguentous products or products of another consistency, which consist almost exclusively of -mineral oil. Highly concentrated petroleum preparations may be reproduced in a very simple and inexpensive manner and in a form in which they may conveniently be used, for instance as an unguent or; the like.

The purity of the products lsdependent upon the degree of purity of the starting materials. Several valuable'products may be produced by treating pure petroleum with bees wax and a mixture of medical soap and alcohol, for instance products which are equivalent to American petroleum jelly and which may be used for all purposes for which hitherto petroleum jelly has been employed. Moreover, petroleum may be converted into the form of a gel and this preparationor the corresponding unguentous preparation may be used for a wide variety of different purposes, for instance for the treatment of chilblains, for surgical treatment, for destroying lice, mosquitos and other insects'and parasites, for promoting the growth of the hair and for several other related purposes. As already mentioned substances of different kinds adapted to exert a special effect may be added tothe preparations during or after the production of thelatter. Powdery preparations produced after the novel process may be used for cosmetic, therapeutic and other purposes. By treating crudeoils technical productsv of high quality may be obtained, for instance lubricating fats and the like. If required or desired the properties ofthe products obtainedmay of course also be improved by subjecting same to purification processes. 1

It can be understood, therefore, from theprior description and disclosureof my invention, that it relates broadly to the productionof unguentous homogeneous, uniformly melting and uniformly resolidifying greases or petroleum jellies from relatively liquid mineral oils by the addition to such oils of relatively small portions of solidifying agents, that is, soap and bees wax. In this general connection, when reference is made in the specification and claims to solidifying agents, I refer to these agentsconsisting of bees waxor .its constituents and soap which cooperatetogeth er to coalesce the oil to form a homogeneous, unguentous, uniformly melting and uniformly resolidifying mass. Ifdesired, in addition to the solidifying agents, portions of paraffin may also he added, but it is essential that at least 1% of bees wax be present which iscaused to'be dispersed and to cooperate with the soap to act in coalescing the oil. The bees wax may be either natural bees wax or its constituents or artificial bees wax, :it being only essential that its active constituents be present.

Having thus described my invention with reference to specific examples drawn to preferred embodiments, which are to be considered as illustrative and notes limiting, sincethe invention is to be limited only by the prior art, what I claim is:

1. A process of producing a solidified oil product, comprising introducing solidifying agents comprising not more than about 5% bees wax into mineral oil while stirring, heating the mass. and diffusing said bees wax with a mixture of soap and an organic solvent while continuously stirring, whereby said oil is converted into an unguentous, homogeneous, uniformly melting and uniformly resolidifying product, the amounts of solidifying, agents not exceeding about 10% of said mineral oil. q

2. A process of producing a homogeneous, unguentous, uniformly melting and uniformly resolidifying grease from a mineral, oil, comprising adding heat to said oil" and with agitation coalescing the same with a solidification agent consisting of a small amount of soap and a small amount of bees wax not exceeding about 5% in substantially equivalent proportions.

4. A process of producing a homogeneous, unguentous, uniformly melting and uniformly resolidifying grease from a mineral oil, comprising adding heat to said oiland with agitation coalescing the same with solidifying agents comprising asmall amount of soap suspended in an organic solvent, and not exceeding about 5% bees ing agents added not exceeding about 10% of said mineral-oil. r I

5. A processof producing a homogeneous, un-

guentous, uniformly melting and uniformly resolidifying grease from a mineral oil, comprising adding a small amount of soap to a mixture of not less than-1% or more thanabout 5% melted bees wax and said oiland intimately combining said components with agitation and heat.

6., A process of producing a powdered solidified oil product, comprising adding heat and diffusing in a mineral oil at raised temperatures solidifying agents comprising not exceeding about 5% bees wax in the presence of a small-amount of soap, the amounts of said solidifying agents not exceeding about 10%, agitating the resultant mass, allowing the mass to cool and adding a pulverulent solid substance to said resultant coalesced homogeneous mass thereby converting said mass into a powdery solid preparation.

'I. A homogeneous, unguentous, uniformly melting and uniformly resolidifying grease comprising a mineral oil containing solidifying agents comprising not less than 1% or more than about 5% bees wax, and soap, said soap cooperating with said bees wax to maintain said bees wax uniformly diffused within the resulting oil mass, the amounts of said solidifying agents not exceeding about 10% of said oil.

8. The process for producing a therapeutic solidified homogeneous mineral oil product havwax, agitating the mass, the amounts ,of solidifyi ing uniformly melting and uniformly resolidifying characteristics comprising diflusing soliditying agents comprising not more than about 5% bees wax in a mineral oil with soap and with added heat, while stirring, the total amounts of solidifying agents not exceeding about 10% of the mineral oil and adding a therapeutic agent whereby upon cooling a soliditled, homogeneous therapeutic unguent is obtained from mineral oil. *9. A powdery, solidified mineral oil product containing a homogeneous, unguentous, uniformly melting and uniformly resolidifying grease containing not less than 1%or more than about 5% bees wax, and soap, said soap cooperating with said bees wax to maintain said bees wax uniformly diffused within the resulting mass, combined with a pulverulent solid.

10. A process of producing a homogeneous, unguentous, uniformly melting and uniformly resolidifyinggrease from a mineral oil, comprising adding a small amount of soap suspended in organic solvent to a heated mixture of not less than t 1% or more than about 5% melted bees wax,
